Hi Aarthy,
That depends on what are you using that calendar for. If the use is going to be some date picking job, several calendar utilities are available...online in Javascript....
You can load one down and plug it into ur JSP....
That's the best way you can get a calendar
Or, if u have any specific task to do with the calendar, get back and we can discuss.
If u want a calendar plug in utility, I have one and can give u with source.
Cheers,
Swamy
